as a bearing for the upper portion of the key 19, and the nut 23 when screwed inwardly on the bolt 21 and against the key gradually forces the upper portion of the key against said member. The plain flat flexed strip or key 19 is capable of effectually securing the head 10 on the sleeve 12, and the bolt and nut afliord very simple and convenient means for flexing the strip or key and holding the same in its flexed con-. dition. The slot 17 is wider at its upper than at its lower end, being approximately wedge-shaped, and hence the upper portion of the key may be moved forwardly against the flat face of the member or, by loosening the nut 23, allowed to recede therefrom.

preferably secure some flexing of the key 19by the drive of the latter into the slots 17, 18 and then attain the additional flexing of the key required by means of the bolt 21 and nut 23, but I may when desired apply a bolt and nut to each end of the key and by means of the same flex both ends of the key forwardly,'as shown in Fig. 5, in which, being a modification, I

' number the head 30, the sleeve 31, the key 32, and the upper and lower key-slots 33, 34 respectively. The head 30 adjacent to the upper slot 33 is formed with a bearing member 35 against which by means of a bolt 36 and nut 37, the upper end of the key 32 may be flexed and held, and said head adjacent to the lower slot 34 is formed with a corresponding member 38 against which by means of a bolt 39 and nut 40,

the lower end of the key 32 may be flexed and held. The construction shownin Fig. 5 will be readily understood without further detailed explanation, and it will be seen that the plain key 32 when held flexed against the sleeve by a bolt and nut at each end may be'rclied upon to securely hold the head. i

The opening 16 in the back of the head 10 and the corresponding opening 41 in the head 30 admit of the middle portions of the keys being readily inspected and also, when necessary, of the head being secured on a sleeve or end of a beam not possessing an annular groove 14 to house the middle portion of the key.' The openings 16, 41 will preferably be of about the same width as the groove in the sleeve and slightly greater in width than the key, as may be understood by reference to Fig. 1.

In respect to that embodiment of my invention employing a spring-key, I do not confine the invention to details of construction further than may be rendered necessary by my claims, the essential consideration being that the plain independent strip or key at one end shall bear against the head and at its middle portion against the part on which the head is secured and that means, as a bolt and nut, shall be provided adjacent to at least one end of the key for enabling the key to be conveniently and to the requisite degree flexed.

In one form of my invention which I illustrate in Figs. 6 to 9 inclusive, I substitute for the spring securing key shown in Figs. 3 and-4 a substantially rigid securing key 42. The brake-head shown in Figs. (Sand 7 is numbered 43 and itjha s a lower opening 44 in its back for the lower end'of the key 42 and an upper member 45 for a bolt 46 which passes through the same and a hole 47 in the upper end of the key 42 and receives a nut 48 bywhich the upper end of the key may be firmly forced toward the member 45 and the middle portion 7 of the key effectually bound against the sleeve 49 on which the head 43 is mounted. The frontwardly facing wall of the opening 44 is convexed and the rear face of the lower end of the key42 is concaved to fit and obtain a firm bearing against said wall, as shown in Fig. 7. The key 42 is slightly.

concave on its front face where it. engages the sleeve 49 for the purpose ofpermltting a reasonably extended surface of the key to bind against said sleeve. slightly less in width than the groove 50 The key 42 is in the sleeve 49, and when on the head 43 said key lies between two flanges 51 formed onsaid head and is exposed at its back ex- 7 ceptat its lower end which is partly concealed behind the'transverse bar or'member 52, against which the lower end of the key has a firm bearing. The key 42 is provided with edge stiffening and strengthening stances a substantially rigid key, as 42, is preferred but in general the spring key,

as 19, has proven to be satisfactory. The head 43 is not only open at upper and lowersides of its backjbut by preference is open flanges 53'and said key is a substantially entirely at its back except at the transverse 7 bar 52. r

What I claim as my invention and desire to secure by Letters Patent, is:

' back and hearing at an intermediate portion against said part-and .atone end against said back, and means for flexing holdmg 1t 1n lts flexed condition,

2. In abrake-beam, the comblnationwith the key and: i
